The Ray-Ban Marshal RB3648 sunglasses bring military-inspired design into modern eyewear with their distinctive hexagonal lenses and bold flat double bridge. Part of Ray-Ban's General Collection launched in 2017, the Marshal sits alongside the General and Colonel models, offering a younger, more geometric take on classic aviator styling. The hexagonal shape creates a unique silhouette that stands out from traditional round or teardrop aviators while maintaining the same versatile appeal.
Lightweight Metal Construction with Flat Temples
Built from durable stainless steel metal, the Marshal features flat temples that reduce weight compared to standard rounded temple arms. This design choice makes them noticeably lighter on your face during all-day wear, while plastic temple tips add comfort around the ears. The flat double bridge isn't just a style statement—it reinforces the frame structure for long-term durability. Adjustable nose pads let you customize the fit to your face shape, and the flex hinge system adds comfort without sacrificing stability.
Prescription-Ready with UV Protection
These sunglasses are prescription-ready, so you can add your Rx lenses for single vision or progressive correction. Available in 51mm and 54mm lens widths with a 21mm bridge and 145mm temples, the Marshal works well for round, oval, heart-shaped, and square faces. All lenses provide 100% UV protection against harmful UVA and UVB rays. The collection includes classic G-15 green lenses, polarized options that cut glare from water and pavement, and gradient lenses that transition from dark to light. The Ray-Ban logo is etched on the lens and appears on both temples.
If you want the look of an aviator but prefer less depth and a more angular shape, the Marshal delivers that balance. The hexagonal design reads as contemporary without chasing trends, making it a solid everyday pair that pairs equally well with casual or dressed-up looks.

Frequently Asked Questions
Are the Ray-Ban Marshal 3648 sunglasses prescription-ready?
Yes, the Ray-Ban Marshal 3648 sunglasses are fully prescription-ready. You can add single vision lenses for nearsightedness or farsightedness, or progressive lenses for multifocal correction. The metal frame construction and full-rim design make them ideal for prescription lens installation.
What size should I choose for Ray-Ban Marshal 3648?
The Marshal 3648 comes in two lens widths: 51mm and 54mm, both with a 21mm bridge and 145mm temples. The 54mm is the more common size that suits most face shapes. You can check your current glasses' measurements (printed inside the temple arm) to compare, or measure across your face at pupil level—a standard credit card is approximately 54mm wide.
Do Ray-Ban Marshal sunglasses have UV protection?
Yes, all Ray-Ban Marshal 3648 sunglasses feature 100% UV protection with a UV400 filter. This blocks all UVA and UVB radiation up to 400 nanometers, providing comprehensive eye protection from harmful rays. The lenses transmit 8-18% of light rays and are dark enough for strong sunlight conditions.
What face shapes work best with the Ray-Ban Marshal 3648?
The Marshal's hexagonal shape works well for round, oval, heart-shaped, and square faces. The angular geometric design adds definition to rounder face shapes, while the adjustable nose pads ensure a comfortable custom fit. The medium to large coverage and flat double bridge create a balanced look across different facial structures.
What's the difference between Ray-Ban Marshal 3648 and Hexagonal 3548?
The Marshal 3648 features a flat double bridge and flat temples for a bolder, more structured look, while the Hexagonal 3548 has a single bridge and rounded temples for a softer appearance. The Marshal is part of the military-inspired General Collection with a more contemporary edge, whereas the Hexagonal offers a vintage-inspired aesthetic.
Are polarized lenses available for the Ray-Ban Marshal 3648?
Yes, the Ray-Ban Marshal 3648 is available with polarized lenses that reduce glare from reflective surfaces like water, pavement, and snow. Polarized options include the classic green G-15 polarized lenses, which maintain natural color perception while cutting reflected glare and reducing eye strain during extended outdoor activities.

Ray-Ban Marshal 3648 vs. Hexagonal 3548N vs. Marshal II 3648M
Choosing between Ray-Ban's geometric metal frames comes down to how bold you want to go and what design details matter most to you.
The Marshal 3648 strikes a balance between classic and contemporary with its flat double bridge and flat temples. The hexagonal lenses offer more coverage than round frames, and the military-inspired double bridge adds structural reinforcement while making a visual statement. It's lighter than you'd expect thanks to those flat temples, and the adjustable nose pads let you dial in the perfect fit. If you want something more distinctive than an aviator but not as trendy as some newer releases, the Marshal delivers.
The Hexagonal 3548N takes a softer approach to the same hexagonal lens shape. With its single bridge and rounded temples, it leans more vintage than the Marshal. The overall aesthetic is more understated—you get the geometric shape without the bold double bridge. It's an excellent choice if you like the hexagonal look but prefer a lighter, more classic vibe that won't dominate your face.
The Marshal II 3648M is the updated version of the original Marshal, adding plastic lining to the hexagonal metal frames. This creates more visual depth and opens up additional color combinations. The core design—flat double bridge, flat temples, adjustable nose pads—remains the same, but the plastic lining makes them slightly heavier and more of a statement piece. If you want maximum impact and don't mind a bolder look, the Marshal II delivers.
Our take: The original Marshal 3648 offers the best balance of distinctive style, lightweight comfort, and versatility. You get the geometric shape and double bridge structure without the added weight of plastic lining, making them ideal for all-day wear. They're bold enough to stand out but not so trendy that they'll feel dated in a few years.
